Descrizione generale

Poly(ethylene glycol) diacrylate (PGEDA) is used for synthesising highly cross-linked hydrogels which are used as biomaterials in tissue engineering. These hydrogels are formed using non-cytotoxic photo initiators. PEG hydrogels can be easily covalently linked to bioactive proteins and peptides which in turn promote specific cell activity either on the surface or within the hydrogel.[1]

Applicazioni

This homobifunctional PEG can be used in hydrogel applications; biocompatibilization; thiol-ene coupling; and other applications using cross-linked PEG networks.

Hydrogels with the ability to change shape in response to biochemical stimuli are important for biosensing, smart medicine, drug delivery, and soft robotics. Here, a family of multicomponent DNA polymerization motor gels with different polymer backbones is created, including acrylamide-co-bis-acrylamide
